Harris also is charged with possession of a stolen firearm and possession or manufacture of an incendiary device. If convicted, he faces 95 to 125 months in prison, prosecutors said in February. If convicted of second-degree manslaughter, Crouchman faces 26 to 34 months in prison. Harris was arrested on an explosives charge just after the incident.

Police say he brought the device and other homemade bombs to the party, then removed bomb-making materials from his Spokane apartment and dumped them in Idaho to avoid investigators.

Crouchman told police he ignited one of the devices in a poorly lighted area, then saw Hathaway emerge from the area and collapse after the explosion.

Medical Examiner Sally Aiken recovered a metal fragment from Hathaway’s neck that appeared to be from a CO2 canister. Aiken believes Hathaway died when the canister struck the left side of his neck and severed an artery and jugular vein, according to court documents.

Harris is represented by James Kirkham. Crouchman is represented by Chris Phelps. Dale Nagy is prosecuting.
